EOR/IOR

Saudi Aramco saw a jump in production for a type of EOR that often takes years to see full benefits.

Carbon dioxide (CO2)/water foams are of interest for mobility control in CO2 enhanced oil recovery (EOR) and as energized fracture fluids or as hybrid processes that combine aspects of both processes.

This article describes how the use of a biological EOR technique that applied produced water for reservoir flooding in a mature field led to rapid and substantial increases in oil production.

This study provides technical analysis of the viability of enhanced-oil-recovery (EOR) processes; the results indicate the potential for significant improvement in recovery efficiency over continued waterflooding.

The label unconventional oil and gas stubbornly hangs on because these formations cannot be understood using the rules of conventional petroleum engineering.

The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR.

A new type of organically modified silica glass that can remove a wide variety of oils and contaminants from produced and flowback water is showing promising results as it undergoes field trials.

The lifespan of a huge, old oil field in Oklahoma is now linked to a fertilizer plant 68 miles away. Chaparral Energy is capturing 45 million ft3/D of carbon dioxide (CO2) that had previously been vented into the atmosphere in Coffeyville, Kansas, compressing it, and sending it via a pipeline.

Changing the salinity of injection water could make the difference in getting more out of existing wells.

Using low-sal water for flood can add 30% to the amount of oil that can be recovered from a reservoir. What is the theory behind it?
